Trusted fire rated sealant in Five Ashes

Fire rated sealant in Five Ashes

Deciding which gaps need fire stopping isn’t our role; your assessor, designer or building control sets that out. What we do is apply the right product to that specification, properly and neatly. If you’re dealing with door frames with gaps between frame and wall and ordinary sealant used where a fire-rated product was needed, we can put it right, on door frames, service penetrations and flats & HMOs alike.

If you have holiday lets, a converted barn used for business or a community building near Five Ashes, the washrooms, kitchens and any fire-rated joints need the same care as a big site.

Our work is backed for twelve months, and the guarantee is the same wherever you are.

Fire rated sealant in Five Ashes: local notes

In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, which is often where open fire-stopping gaps are first noticed. We work to the specification you are given, installing the product to its tested details.

Managing a site like Five Ashes CofE Primary School? Then service openings in fire-resisting walls need checking after any refurbishment. If you look after a church, hall or community building such as Church of the Good Shepherd, service openings in its walls need the right fire-rated sealant, as in any building.

Aftercare tips

How long the joints last depends on use and care. Here’s what we suggest:

  • Make resealing part of every contractor’s brief
  • Never patch a fire seal with standard sealant
  • Get damaged fire seals looked at promptly
  • Keep pictures of seals that will be hidden

Do not add foam, filler or ordinary sealant over a fire seal. If it needs repair, use the same type of product. We can tell you which product we used.

Open gaps do not only matter in a fire: noise, draughts and even pests can come through too. Dealing with them early helps with all of these.

When to call us in Five Ashes

Sealant applied too thin, without the backing its detail needs, or onto dust won’t perform as it was tested. Rushed fire stopping is common particularly when it was the last job before handover.

Any of these means the joints need attention:

  • Joints picked up in a fire-stopping survey
  • Door frames with gaps between frame and wall
  • Gaps filled with a product that is not fire-rated
  • Linear gaps at the head of walls

Rented homes near Crowborough station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

FAQs for Five Ashes

Will you come out to Five Ashes?

Yes, Five Ashes is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Can you do fire rated sealant in Five Ashes?

Yes, Five Ashes is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or email us and tell us what needs doing.

Do you do fire sealant around door frames?

Yes. We often seal open gaps hidden behind the architrave. The door and its fittings are a separate job for a door specialist.

Will it make a mess?

Very little: the area around the joints is protected first, and we tidy up before we go.

Do you take on fire stopping in schools and offices?

Yes, in flats, HMOs, schools, offices and other buildings, occupied or empty. Tell us how the building is used and we’ll plan around it.

How long does fire rated sealant take?

As a guide, most jobs take a few hours for a handful of gaps, and longer for a whole building. Bigger jobs take longer, and we will say how long yours will take.

How much does fire rated sealant cost in Five Ashes?

There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before work begins.

What fire rating will the seal have?

We do not issue ratings or certificates ourselves. What’s required is set by your assessor or designer, and the product’s tested details show what it achieves; we install to those details and record what we did.

DIY versus a professional finish

The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Leave it or put it right?

For some gaps, sealant is not the right answer and another system is needed. Large holes, cable bundles and plastic pipes can call for batts, collars or wraps. If a gap isn’t suitable for sealant, we’ll tell you. Around Five Ashes, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

Why us?

  • We never seal over old sealant
  • Experience in homes, commercial sites and hotels
  • We leave the area clean and tidy
  • Anti-fungal silicone where joints get wet

  3. Dust and loose debris are cleaned from each gap.
